What is the main function of the Security Heartbeat in Sophos XG Firewall?

The main function of the Security Heartbeat in Sophos XG Firewall is to assess the health status of endpoints. This feature provides real-time reporting on the security posture of endpoints within the network, allowing the firewall to make informed security decisions based on the endpoints' compliance with policies. When endpoints are healthy and in compliance, they can communicate freely, while those that are facing security issues can be isolated or treated differently based on predetermined policies. Thus, the Security Heartbeat plays a crucial role in maintaining the overall security environment by ensuring that all devices connected to the network are adequately protected and monitored for any signs of compromise.
